EXTENSION-TABLE.

i Specification of Letters Patent. l v patiente@ Junta'ylfgl,

.t Application ined December 4, 191e.A serialv No". 3423121 have invented a certain new and' useful' Extension-Table, of which the following is a specification.

This invention relates to extension table-s, and particularly to that typef wherein the extension leaves are carried directly by the table', and which' is distinguished from those in connectionl with which loose leavesare provided and set whollyl manually into place upon separation of the tabletop sections, the former type of tables being usually adapted tov set inthe leaves automatically or semi-automatically uponthe separa'- tion of the table-top sections. The looseleaf tables are usually round when in folded state and are extended to an1oval-like elongated con'guration, while the tables of the saidfautomati'ctyp'e are soV contrived that they have to be builtin square-or rectangul'ar shapes, and as round shaped tables are much more advantageous than the rectangular tahles, the'latter are deemed:v objectionable, as evidenced byV the almost universal use in dining-rooms' of round extension tables at the present time.

The' principal object of ymy invention 1s to provide a simple', inexpensive, economically and conveniently manufacturable, conveniently utilizable, strong, durable, rehable, efficient, andv improved extensiontable of thel above mentioned type.

' Another object is to provide' an' extension table ofthe said type, which will be round when in the folded' or contracted position, but which when extended will assume an elongated form exactly similar to that of the extended tables which utilize loose leaves in their operation.

Other objects' and advantageswill hereinafter appear.

In the accompanying drawings,-

Figure 1 shows a general sectional elevation of the extension-table.

Fig. 2is a bottom plan vview of the table shown in F ig.y 1.

Fig. 3 shows adetail of the extensiontable.

To the post 1, mountedv upon a base 2, is secured; an extension-leaf13, on top ofwhich normally rests a pairof usual semi-circular table-top sectionsV 4, 5, When the table is in folded` condition. yF or convenience of illustration the post 1 is shown` broken away and connected with the: leaf 3 by thel dash and' dot lines 11a. vvRails 7 are 'securedf tothe underside of the leaf 3l and extend beyond its'sides 8, and filler boardsf9, 10"'securedl to Y the undersidesV of the sections 4, V5, respectively' rest' upon said rails. when the sections are located on ztopof the 1eaf4'3 in the folded condition of the table, whereby the rails 7 andi boards 9,"10Hserve tov provide iir'm support for the table-sections' 4, 5- beyond' the' leaf wheny the latter are in their foldedcondition'yin which statethey rest but partially on toppof the leaf 3, as indicated' by the section 4 inFig. 1f. Tothe 4underside of the board 9 is secured a pair of guiderails 11 which extend* therefrom underneath the leaf 3v andare located against thesup` port-rails 7 adjacent their inner sides 12 that face eachother, and similar guide-rails 13 secured to' the VVboard 10 are located against the railsl 7 adjacent'their opposite sides 14. Normally or when the `table is in folded conditionv its sections 4, 5 are located onl top of the leaf 3v with Vtheir edges 15 adjacent'V each other and thereby constitute` regular round-shapedta'ble, asshownin Fig. ,2; Whenit is desired to extend,V the table, the: sections*4 ,5 are drawn away from eachother and slid along the leaf 3 until theedge's` 15 of the sections pass by the' edges 83of the leaf, whereupon the sections drop down kupon the support railsk 7 and rest thereon on a level with the leaf 3',A as" indicated by the position of the section 5 in' Fig. 1.V As the top-sections 4, 5 drop down to the level'y of the leaf 3 and the guide-rails'll, 13 come down there-with', pins llocated at the extremities ofY said rails and forming part thereof'e'nter int'o yoltes 17 of hooks 18 secured to the underside of leaf 3, andinthis manner these` pinsI lockl ythe top-sections against further extension and also maintain said sectionsinfirm-state againstV any swinging or downward dislocation ofJ their ends 19. In order' to again fold the talole it' vrequires merely a slight lifting of the end 19 ofeaeh top-section, to bring'it'sunderfsurface on-a level with the top of leaf 3, andV then sliding the section along said leaf until it reaches the center thereof,l the pins 16 leaving'the yokes 17 andtherebyreadilyunlocking' from' the hooks 18'at theV very commencelnent of the sliding ofthe top-sections y toward' each other.

The length ofthe leafl 3 is less than the extent of the diameter of the table, in order that the leaf may be completely 'encom-y passed by the siderail 6 of the table-top, and hence when the table is extended a gap vis left at each end of theleaf bounded by' the edge 20 thereof and the edges 15 of the top-sections. To each. edge 20 of leaf 3 is Vhinged a board 21 which isV normally lmainpivoted to the leaf, to a position rightangularly to therboard 21, as shown by the dash and dot lines. When the table-is extended,

therefore, the board 21y is swung to the position shown by the dot and ,dashl linesand the said gap is completely'V closed up, so that the endof the'leaf 3 assumes a form which renders it tangent vto the semicircular table sections, and theeentire extended table acquires' a form similar to that of the extended tablesusing common loose leaves, Before folding'V the table the latches 23 are swung Y back to the position shown andthe springs l leaf fixed to said means, a pair ofv sections l22 thereupon swing the boards 21 tothe inoperative position 'shown underneath the leaf 3, after which the table sections 4, 5 may be brought together to fold up the table., l Y

It willbe evident thatv the table top is at all times firm against any downward vdislocation, since inthe folded condition the sectionsll, 5 rest upon the leaf 3 and through the boards 9, 10upon the rails 7 and the guide rails'll, 13 prevent any downwarddislocation of thetable ends 19'; while when saidsections are in extendedposition they rest firmly directly upon the rails 7 and the rails 11, 13 coperatewith the hooks 18 to. prevent downward dislocation of said tableV ends; the post 1, leaf 3, and rails 7 being permanently firmly secured together.`
